Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
I bought this in a medium which was made for a ten year old. Then, I bought an extra large and, again, designed for a child. Once over your head, it is impossible to get the back pulled down to the waste without help. This is a don't buy item.
